origin of friendships

Do you have any friends with whom you share no institutional background? (aikido counts I think)
-apropos our talk about dates as interacting without context. -and our talk about high school. -and it goes to thinking about community...
Walking home from work tonite, I could not think of any friend I did not work with or go to school with. interesting - bcs I think of myself as tending toward one-to-one, non-context-dependent relations. and sure, some of my friendships have actually formed after the shared context is over - I've become friends with people that I did not know while at the institution. and (implicit in that anyway) with people that I did not actively share the experience with. but in every case -Every! I can't think of an exception- my friends did once work somewhere I worked or attend a school I attended.
Not a one that I met at a party or 'through mutual friends.' which, okay, it's not like I'm much for attending gatherings. butI ~picture myself as open to encounters of the 'bumping into on the street' sort. but, no, not one relationship with such a beginning.
does not bode well for forming new relationships through adulthood, does it?
So, no man is an island or something. rather: if you are an island, you are not going to know any other islands.
or in fact we are islands and it takes an ocean to make it us a world. no - not (natural) oceans but (constructed) bridges / or what do you call it when land is created where there was water. Donne really has little application here but it's what comes to mind.
the point, maybe, is that institutions are pretty important.
I can imagine that I have not found them satisfying; however, but for my schools and bookstores I would have no relationships except family. and relationships make the person, right.
